By now you have gathered that you are not the only one totally confused. Most consumers are confused, myself included. Sony appears to be not supporting SACD by not issuing them as hybrids, and of course DVD-A discs (unless they are the new dual discs) will not play on a CD player.
Most DVD-As list if they have a stereo hi-rez layer as well as multi-channel layers, but on many players it is nearly impossible to tell if you are accessing the front channels of the multi-channel layer or the stereo layer unless you go through 2 set up screens, one for the player and another for the disc-which of course is absurd for anyone interested in 2 high quality 2 channel stereo.
The picture is fruther confused by many universal players not actually capable of hi-rez (see the review of the McCormick player in a recent Sterophile), and the fact that many discs don't really contain any higher rez than a good red book CD.
Overall a ridiculous situation for the consumer.
